LED Counter in Python on the Pi

Just a quick post to show a video clip of my Raspberry Pi controlling a seven segment LED via the Pi's GPIO port. I plan to extract the code into a reusable library. One possible use will be to display status / error codes whilst controlling other devices. Must stop playing with hardware and get back to the software.

DevWeek 2013

Well it’s that time of year again, they seem to fly by these days. I’ll be off to DevWeek again soon. I’m booked in for the three day’s so looking forward to some interesting sessions. I get to travel into London by train so that’ll give me forty minutes of thinking time for new programming projects. I can finally see some light at the end of the tunnel with all the work I’m doing at home at the moment. In about a month’s time I should be able to concentrate on some game programming. I need to get started with some proof of concept ideas I have for my new Spectrum game. I’ll release more details once I’ve got enough code to produce a video or demo. If anyone reading this is going to DevWeek and wants to talk Z80 then let me know.

From one LED to seven

Another weekend and another hour spent with my Raspberry Pi. After a rummage about in my junk box I located a seven segment LED. Annoyingly the device was too small to span the gap on my breadboard. About ten minutes later I had fabricated a suitable socket. Once the Pi was fired up I wrote a quick bit of Python to check that I could control all the segments. As you can see from the photograph, this was a success. Next Sunday’s coding session will be to allow me to pass in a number via the command line and have the device display the correct number.
